Create a software for simulation of robotic arm

Well I am in Petnica, the Sience Center in Valjevo, Sertbia. My project is "simulating a robotic arm in 3 dimension". I have no idea how could I do it. So, what do you think? Could I do anything with VB? A lot of my friends here think it is inpossible and that I have to start learning some other programming language
